Speaking to a petroleum industry audience in Houston recently, Environmental Protection Agency Administrator Gina McCarthy said, “we can and we must do more to reduce methane emissions in the oil and gas sector.” McCarthy has it right. Uncontrolled leaking and venting of natural gas wastes a valuable resource and threatens our climate. Last week, as part of a joint announcement with Canada, the administration said it plans to move forward on a solution.

For a blueprint on solving this problem, EPA should take a look at Pennsylvania, where Gov. Tom Wolf (D) recently proposed comprehensive new methane emissions standards for oil and gas companies in his state.
